Question

当我提交表单时出现此错误：

执行＆＃39; INSERT INTO技能（名称）VALUES（？）＆＃39;时发生异常。与params [null]：

我在modal ..page x.html.twig内容名称（SkillType）和级别（选择选项）中使用modal i加载页面x.html.twig。

我有这个表格类型：

xxx

和SkillType是：

<?php

        namespace AppBundle\Form\Type;

        use AppBundle\Entity\CandidateSkill;
        use Symfony\Component\Form\AbstractType;
        use Symfony\Component\Form\FormBuilderInterface;

        use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
        use Symfony\Component\Form\Extension\Core\Type\SubmitType;
        use AppBundle\Form\Type\SkillType;
        use Symfony\Bridge\Doctrine\Form\Type\EntityType;


        /**

         */
        class CandidateSkillType extends AbstractType
        {
            /**

            public function buildForm(FormBuilderInterface $builder, array $options)
            {
                $builder->add('level', ChoiceType::class, array('choices' => array('Beginner' => 'Beginner', 'Confirmed' => 'Confirmed', 'Senior' => 'Senior', 'Expert' => 'Expert')))
                ->add('skill', SkillType::class)->add('Create', SubmitType::class, array('attr' => array('class'=>'skill btn btn-fill btn-rose')));
            }

            /**

            public function configureOptions(OptionsResolver $resolver)
            {
                $resolver->setDefaults(array(
                    'data_class' => CandidateSkill::class,

            {
                return 'appbundle_candidateskill';
            }
        }

                    <div class="card">

                            {{ form_start(form, { 'attr' : { 'class': 'theFormskill' } }) }}

                            {{ form_end(form) }}
                        </div>
                    </div>

                </div>
                </div>


     <script>
    $( function() {

        var availableTags= [];

        {% for skill in all%}

          availableTags.push('{{skill.skill.name}}');

        {% endfor%}
        console.log(availableTags);
        $( "#appbundle_candidateskill_skill_name" ).autocomplete({
          source: availableTags
        });
      } );



    $( ".skill" ).click(function() {
        $(".theFormskill").ajaxForm({url: "{{path('recurit_canddiate_skill_new')}}", type: 'post'});
    });

     </script>

create form和getData的函数句柄：

/**
     * Creates new CandidateSkill Object.
     *
     * @Template()
     * @Route("/add-candidateskill", name="recurit_canddiate_skill_new")
     *
     * @param Request $request
     *
     * @return array|\Symfony\Component\HttpFoundation\RedirectResponse
     */
    public function newAction(Request $request)
    {
        $candiateSkill = $this->getHandler()->post($request->request->all(), $request->isMethod(Request::METHOD_POST));

        if ($candiateSkill instanceof CandidateSkill) {
            return $this->redirectToRoute('fos_user_profile_show');
        }

        return ['form' => $candiateSkill->createView(),'all'=>$this->getHandler()->all()];
    }

当我为$ form转储时，＆gt; getData（）..数据为空

功能保存：

 /**
         * {@inheritdoc}
         */
        public function handle($object, array $parameters, string $method, bool $submited = false, array $options = [])
        {
            $options = array_replace_recursive([
                'method' => $method,
                'csrf_protection' => false,
            ], $options);
            $form = $this->formFactory->create(get_class($this->formType), $object, $options);
            if (!$submited) {
                return $form;
            }
            $form->submit($parameters, 'PATCH' !== $method);

            return $form->getData();
        }

当我在CandidateSkillHandler中的函数post（）中...错误已经在

$这 - ＆GT; repository-＆GT;保存（$ candidateSkill）;

Answer 1

我们在devit2017中发现这个表格没有用，因为请求没有得到处理。

这些行

$request = $this->requestStack->getCurrentRequest();
$form->handleRequest($request);

而不是

$form->submit($parameters, 'PATCH' !== $method);

解决这个问题。

提交表单后的值为null
